 machines for 15 years.

 in adding improvements 

 to what will always be 

 the true model of a

QUERY. 



Can any reader of Science cite 

 a case of lightning stroke in 

 which the dissipation of a small 

 conductor (one-sixteenth of an 

 inch in diameter, say,) has failed 

 to protect between two horizon- 

 tal planes passing through its 

 upper and lower ends respective- 

 ly? Plenty of cases have been 

 found which show that when the 

 conductor is dissipated the build- 

 ing is not injured to the extent 

 explained (for many of these see 

 volumes of Philosophical Trans- 

 actions at the time when light 

 ning was attracting the attention 

 of the Royal Society), but not 

 an exception is yet known, al- 

 though this query has been pub- 

 lished far and wide among elec- 

 tricians.

A BUSINESS MAN'S HAND-BOOK. 



The report of the Postmaster General, Just issued, 

 states that nearly S2,000,000 In checks, drafts and 

 money, reached the dead- letter office during the 

 present year through Improper addressing— more 

 than one-half from New York State. Probably 

 double this sum has been lost through delays and 

 accidents resulting from carelessness In mailing 

 and corresponJence. To reduce these errors to a 

 minimum, the Government Issues THE UNITED 

 STATES OFFICIAL POSTAL GUIDE, in an annual 

 number published in January, and monthly supple- 

 ments, a book of 900 pages, containing three classi- 

 fied lists of the 66,000 post-ofBces in the Union, to- 

 gether wilh postal rules and mail regulations. 

 Every merchant, wholesale dealer, manufacturer 

 and professional man having correspondence, will 

 find the Guide indispensable. It is also of great as- 

 sistance in translating illegible writings to lawyers, 

 printers and others. No establishment where ac- 

 curacy and care are observed as rules is complete 

 without it. The price of the GUIDE in paper is 

 $2.00, in cloth, S2.50. Orders in New York State 

 should be sent to HOME AND COUNTEY, 93 Maiden 

 Lane, New York; outside of New Y'ork State to Geo.

PROPRIETARY. 



The casting out of the devii 

 of disease was once a sign 

 of authority. 



Now we take a little more 

 time about it and cast out 

 devils by thousands — we do 

 it by knowledge. 



Is not a man who is taken 

 possession of by the germ of 

 consumption possessed of a 

 devil ?
